Patent-Ansprüche:
1. Die Trennung der Mechanismen, weiche das Auf- und Niederschrauben der Platten α bewerkstelligen, von denen welche das Anpressen an ihre Dichtungsflächen hervorrufen, wodurch erreicht wird, dafs letzterer Mechanismus durch keinen Zufall eher zur Wirkung gelangen kann, als bis die Platten sich ihren Dichtungsflächen gegenüber befinden, was die Anwendbarkeit dieses Ventils in jeder Lage ermöglicht und daher von grolser Wichtigkeit ist. (Bisher konnte dies nicht geschehen, da bei den üblichen Constructionen der Ventile mit parallelen Dichtungsflächen die Platten durch ihr Eigengewicht nach unten fallen mufsten, und nur der sie auseinander pressende Keil mit der Schraubenspindel in directem Zusammenhange stand).
2. Das Anpressen der Platten α an ihre Dichtungsflächen mit Winkelhebeln, wodurch ohne bedeutende Reibungsverluste eine gute Dichtung bei vollständig parallelen Dichtungsflächen des Ventils erzielt wird.
